22. An Earth satellite is orbiting at a distance from the Earth's surface equal to one Earth radius (4000 miles). At this location, the acceleration due to gravity 13 what factor times the value of g at the Earth's surface? a. There is no acceleration since the satellite is in orbit. b. 2 c. 1/2 d. 1/4 23. An object that is orbiting the Earth at a height of three Earth radil from the center of the Earth has a...
Determine the ratio of Earth's gravitational force exerted on an 80-kg person when at Earth's surface and when 1000 km above Earth's surface. The radius of Earth is 6370 km.
Suppose an object is launched from Earth with 0.52 times the escape speed. How many multiples of Earth's radius (RE 6.37 x 106 m) in radial distance will the object reach before falling back toward Earth? The distances are measured relative to Earth's center, so a ratio of 1.00 would correspond to an object on Earth's surface. For this problem, neglect Earth's rotation and the effect of its atmosphere For reference, Earth's mass is 5.972 x1024 kg. Your answer is...
An object located 3 earth radii ABOVE the earth's surface has a gravitational field of g/16 where g is the value at the earth's surface. true or false?
An object located 3 earth radii ABOVE the earth's surface has a gravitational field of g/16 where g is the value at the earth's surface. true or false?
A space elevator has an altitude above the Earth's surface of 40,000 km. What would be the kinetic energy of a 1kg mass at the end of our space elevator? What would be the gravitational potential energy of that mass? If the 1 kg object fell all the way down to the Earth's surface, what would be its speed just before impact? (The radius of Earth is 6.4 x 106 m).
QUESTION 10 A rocket of mass 2000 kg is launched straight upwards from the Earth's surface to an altitude of 10,000 km. How fast was the launch speed? Radius of the Earth is 6.37x10 m. Mass of the Earth is 5.97x10 kg. The Universal gravitational constant is 6.67x10" N /kg a 442.7 m/s Ob. 1390 m/s c.4119 m/s d. 8739 m/s Oe. 10841 m/s
If an object weighs 1300 N on earth's surface, what would be the approximate weight of an object on the surface of a planet with 8 times the mass of earth and 10 times the radius?
P3. A rocket of mass -1.20x10'kg is launched vertically upward from point A on the earth's surface with an initial speed v, 7.00km/s a. (12) Calculate the maximum height H of point B above the earth's surface at which the rocket will momentarily come to rest, before it starts falling back to the earth Hint: Use conservation of energy. b. (4) Determine the gravitational acceleration a at point B. c. (9) Calculate the total mechanical energy E of the rocket....
